Should You Incorporate Your Business in Canada? (2026)

At some point, every Canadian business owner hears the same advice: “You should incorporate.” Usually from someone who incorporated their own business and swears it saves them a fortune in taxes.

Sometimes that’s true. Sometimes it’s not.

Incorporation is the single most consequential structural decision you’ll make for your business. It changes how you’re taxed, how you’re paid, your personal liability, how the CRA views you, and what you can and can’t do with your business income. Getting it right can save you tens of thousands of dollars over the life of your business. Getting it wrong — or getting it right at the wrong time — can cost you more than staying as a sole proprietor.

This guide breaks down what incorporation actually means in Canada, the real tax math, the costs, the drawbacks, and how to decide if it’s time.

Sole Proprietorship vs. Corporation: What’s Actually Different?

When you operate as a sole proprietor, you and your business are the same legal entity. Your business income goes on your personal tax return (T1), you’re taxed at your personal marginal rate, and you’re personally liable for all business debts and obligations. If you’re currently a sole proprietor, make sure you’re claiming every deduction available — see our guide to 17 tax deductions for self-employed Canadians.

When you incorporate, you create a separate legal entity — a corporation. The corporation earns the income, pays corporate tax, and then you pay yourself from the corporation (either as salary or dividends). You file a separate corporate tax return (T2), and the corporation has its own legal responsibilities.

Here’s a side-by-side comparison:

The Tax Advantage Everyone Talks About

The primary reason people incorporate is the small business tax rate. In Canada, the first $500,000 of active business income earned by a Canadian-controlled private corporation (CCPC) is taxed at significantly lower rates than personal income.

Federal + Provincial Combined Corporate Tax Rates (2025)

Compare that to personal marginal tax rates. If you’re a sole proprietor in Ontario earning $200,000 in business income, your combined federal and provincial marginal rate on income above $110,000 is roughly 43–46%. The same $200,000 earned inside a corporation would be taxed at 12.2% at the corporate level.

That’s a massive difference in the amount of tax paid today. But — and this is the part people miss — the money is still inside the corporation. To get it into your personal bank account, you need to pay yourself, and that triggers additional tax.

The Part Most People Get Wrong: Tax Deferral vs. Tax Savings

Incorporation doesn’t eliminate personal tax. It defers it.

Here’s the real math for Ontario:

Scenario: $200,000 in business income, you need $100,000 to live on

As a Sole Proprietor:

• All $200,000 is taxed on your personal return
• Federal + Ontario tax: approximately $56,000
• Take-home: approximately $144,000

As a Corporation:

• Corporation earns $200,000, pays 12.2% corporate tax = $24,400
• $175,600 remains in the corporation
• You pay yourself $100,000 in salary → personal tax of approximately $25,000
• Total tax paid this year: ~$49,400
• $75,600 remains in the corporation, taxed at only 12.2%, available for reinvestment

The $75,600 left in the corporation is where the tax deferral happens. You’ve paid only 12.2% on that money instead of 43%+. If you leave it in the corporation to reinvest in the business, invest in a portfolio, or save for a future expense, you’re earning returns on money that would otherwise have gone to the government.

But the moment you take that money out — as dividends, salary, or by winding up the corporation — personal tax is triggered. The Canadian tax system is designed so that, in theory, the total tax paid (corporate + personal) is roughly equivalent to what you’d pay as a sole proprietor. This is called integration.

In practice, small differences in integration mean you might pay slightly more or slightly less depending on your province and how you structure your compensation. The real advantage is the deferral and the ability to control when you take the income.

When Incorporation Makes Sense

Incorporation is worth the cost and complexity when:

1. You’re Earning More Than You Spend

This is the threshold that matters most. If your business earns $150,000 but you need $140,000 to cover your living expenses, there’s very little income left in the corporation to defer. The overhead of incorporation (accounting, legal, annual filings) may cost more than the tax deferral saves.

Rule of thumb: Incorporation starts making clear financial sense when your business consistently earns $75,000 to $100,000+ more than you need to live on.

2. You Want Liability Protection

If your business carries risk — you have clients, employees, contractors, a physical location, or you give professional advice — incorporation creates a legal barrier between business liabilities and your personal assets. A lawsuit against the corporation generally can’t reach your home, personal savings, or other personal property.

This isn’t bulletproof. Lenders often require personal guarantees, and directors can be personally liable for certain obligations (like unremitted payroll taxes and GST/HST). But it’s significantly better protection than a sole proprietorship, where there’s no separation at all.

3. You Plan to Sell the Business

The Lifetime Capital Gains Exemption (LCGE) allows you to shelter up to $1,016,836 (2025 amount, indexed annually) of capital gains from the sale of qualifying small business corporation shares — completely tax-free. This exemption is only available for shares of a corporation, not for a sole proprietorship.

If there’s any chance you’ll sell your business in the future, this alone can be worth hundreds of thousands of dollars in tax savings.

4. You Want to Income Split (Within the Rules)

Since the 2018 Tax on Split Income (TOSI) rules, income splitting through a corporation is more restricted than it used to be. But it’s still possible in certain situations, particularly when family members are actively involved in the business (working 20+ hours per week).

Paying a reasonable salary to a spouse or adult child who works in the business remains a legitimate strategy.

5. You Want a Professional Structure for Contracts

Some industries and clients require you to work through a corporation. Government contracts, larger corporate engagements, and certain professional designations (doctors, lawyers, accountants) may require or benefit from incorporation.

When Incorporation Doesn’t Make Sense

Don’t incorporate if:

• Your income is under $80,000 and you spend most of it. The accounting fees alone ($2,000–$5,000/year for corporate bookkeeping and a T2 return) may exceed any tax benefit.
• You have significant employment income and your side business is small. The small business deduction is only available on active business income, and the complexity isn’t worth it for a small side hustle.
• You need all the money immediately. If every dollar your business earns goes directly to personal expenses, there’s nothing to defer.
• You’re a commissioned employee misclassifying yourself. The CRA actively audits personal services businesses (PSBs). If your corporation has essentially one client and the relationship looks like employment, the CRA can deny the small business deduction and tax the income at the general corporate rate (~26.5%) with no small business deduction — worse than being a sole proprietor.

The Real Cost of Incorporation

One-Time Setup Costs

• Federal or provincial incorporation: $200 (online, federal) to $400+ (provincial, varies)
• Legal fees (if using a lawyer): $1,000–$2,000+
• Minute book and corporate setup: Often included in legal fees, or ~$200–$500 if done separately
• Business number registration: Free (done through CRA)

Annual Ongoing Costs

• Corporate tax return (T2): $1,500–$3,000+ per year (accountant prepared)
• Bookkeeping: $200–$500/month depending on volume
• Annual provincial filing: $0–$50 depending on the province
• Payroll setup and filings (if paying yourself salary): Additional time and compliance
• HST/GST filings: Required if revenue exceeds $30,000 (same as sole proprietorship)

Total annual cost of maintaining a corporation: Roughly $4,000–$10,000, depending on complexity. This is on top of what you’d spend as a sole proprietor.

How to Incorporate: The Process

If you’ve decided incorporation is right for your business, here’s the process:

1. Choose Federal or Provincial Incorporation

• Federal (through Corporations Canada): Gives you the right to operate under your corporate name across all provinces. Cost: $200 online.
• Provincial (through your province’s registry): Limits your name protection to one province. Cost varies ($300–$500+).

Most small businesses incorporate federally unless they only operate in one province and want a simpler process.

2. Choose a Corporate Name or Use a Numbered Company

A named corporation (e.g., “Smith Consulting Inc.”) requires a NUANS name search ($13.80) to confirm the name is available. A numbered corporation (e.g., “12345678 Canada Inc.”) skips this step and is faster to set up.

3. File Articles of Incorporation

Done online through Corporations Canada (federal) or your provincial registry. You’ll specify:

• Corporation name
• Registered office address
• Directors (at least one, must be a Canadian resident for federal corps)
• Share structure

4. Set Up the Corporation

After incorporation:

• Create the minute book (corporate records: bylaws, director resolutions, share certificates)
• Register for a business number with the CRA
• Open a corporate bank account
• Register for GST/HST and payroll accounts as needed
• Set up bookkeeping from day one

5. Choose Your Compensation Strategy

Work with an accountant to decide the right mix of salary vs. dividends. This decision affects your CPP contributions, RRSP room, personal tax rate, and corporate tax. It’s not a one-size-fits-all answer — it depends on your income, your personal situation, and your goals. If you’re weighing salary (which builds RRSP room) against dividends, our RRSP vs TFSA guide explains how contribution room affects your tax strategy.

The Bottom Line

Incorporation is a powerful tool for the right business at the right time. It’s not a magic tax shelter, and it’s not right for everyone. The decision should be based on math, not assumptions.

The questions that matter are:

1. How much does your business earn above what you need to live on?
2. How long can you leave money in the corporation?
3. Do you need liability protection?
4. Do you plan to sell the business eventually?
5. Does the ongoing cost of maintaining a corporation make sense for your revenue?

If you’re unsure, the best investment you can make is a one-hour consultation with an accountant who can run the numbers for your specific situation.
